On Monday, authorities offered new details that confirmed what neighbors said they witnessed: McMeen shot her children and took her own life in the open backyard of her home in the rural community about 90 miles southwest of Chicago. Warren was shot inside, police said. The gunfire started minutes after Skyler and Ian arrived home from school on the last day before Christmas break.

Autopsies determined that the 10-month-old was shot twice in the head; her father, Warren, died of gunshot wounds in the back and in the neck; Skyler was shot twice in the head and once in the upper back, and Ian was shot in the head, Livingston County Coroner Michael Burke said in a news release. McMeen died of a self-inflected gunshot wound in the neck, the release said. Police found the semi-automatic 40-caliber handgun next to her hand, according to the release.

Police said they still were investigating and would not offer details on a possible motive, though they are looking for anyone who spoke with McMeen or Warren before the shootings.

In the quiet community of about 100 people, residents created a memorial of wreaths and candles at the home in the 100 block of South Street, Emington Mayor Daniel Delaney said.

He said he hopes the town, which has a grain elevator, a church, a post office, a park and a dog-grooming business, doesn't get a bad reputation.

"We've been working so hard on this little town to make it appealing to get people interested in coming here," Delaney said.

A visitation for Warren and his daughter, Maggie, will be held from 5 to 8 p.m. Wednesday at Fruland Funeral Home, 121 W. Jefferson St., Morris. Funeral services will be held at 10:30 a.m. Thursday at the funeral home.
